Summary Introduction
To review:
The importance of pollen tube in the process of
Introduction:
The pollen grain or the male microgametophyte consists of two cells. One is called tube cell and other one is a generative cell. The tube cell leads to the formation of the pollen tube, which is directly related to the landing of microgametophyte on the stigma of the female reproductive organ, that is, carpel.
